Information about the public boat launch area at the Giant Mine site

This figure shows a map of the part of the Giant Mine site on which the existing public boat launch and Great Slave Sailing Club remain operational. A blue line that encompasses the sailing club, the Yellowknife Historical Society museum’s historical assets, public parking, the townsite, an existing gate and the water treatment plant outfall. A black line with dots along the old Ingraham Trail notes an existing fence. The water treatment plant outfall is shown going into the water of Yellowknife Bay. The plant outfall, the existing gate, the townsite and an area surrounding the public parking are shaded in orange to demonstrate where remediation activities are taking place during Phase 1. The legend notes these activities as the townsite deconstruction (complete), the water treatment plant outfall construction (2023 and 2024), and the deconstruction of the commissary building (2025 and 2026). The public parking, existing public boat launch, Yellowknife Historical Museum, the museum’s historical assets and the Great Slave Sailing Club are in an area shaded in green to denote public and leaseholder use. A green line to those areas shows the public use roadway. Parallel to this line and extending into the orange shaded area, an orange dashed line delineates roadways for remediation use. In Yellowknife Bay, 28 mooring locations are also marked.

This figure shows a map of the part of the Giant Mine site on which the existing public boat launch will remain open while the interim public boat launch area is closed during remediation activities. A blue line that encompasses both these areas as well as the Yellowknife Historical Society museum’s historical assets, public parking, the townsite, an existing gate and the water treatment plant outfall. A black line with dots along the old Ingraham Trail notes an existing fence. The water treatment plant outfall is shown going into the water of Yellowknife Bay. The nearshore sediment cover, the closed interim public boat launch are down to the road and around the Yellowknife Historical Society Museum but not the museum building itself are shaded in orange to demonstrate where remediation activities are taking place during Phase 2. The legend notes these activities as removing contaminated soil and buried waste, if buried waste is encountered, constructing the new interim boat launch and floating dock, partially dredging or placing an engineered rock cover over the contaminated sediments, or both, and reconstructing access roads and parking areas. The public parking, existing public boat launch, Yellowknife Historical Museum and the museum’s historical assets are in an area shaded in green to denote public use. A green line to those areas shows the public use roadway. Parallel to this line and extending into the orange shaded area, an orange dashed line delineates roadways for remediation use. A red diamond on the road toward the museum shows where traffic control will be set up. In Yellowknife Bay, 28 mooring locations are also marked.

This figure shows a map of the part of the Giant Mine site on which the new interim public boat launch will remain open while the existing public boat launch area is closed during remediation activities. A blue line that encompasses both these areas as well as the Yellowknife Historical Society museum’s historical assets, public parking, the townsite, an existing gate and the water treatment plant outfall. A black line with dots along the old Ingraham Trail notes an existing fence. The water treatment plant outfall is shown going out into the water of Yellowknife Bay. The nearshore sediment cover near the boat launch, the new, open interim public boat launch area down to Yellowknife Historical Society Museum are shaded in green to demonstrate public access while remediation activities are taking place during Phase 3. In orange, more than half the map is show as undergoing remediation activities; within this area is more new sediment cover along the shore of Yellowknife Bay, the new Baker Creek alignment, a bridge over the creek, the water treatment plant outfall, the townsite, an existing gate, Baker Creek wetland and a new drainage channel. The legend denotes remediation activities as partially dredging or placing a engineered rock cover or both over contaminated sediment, removing contaminated soils, remediating Baker Creek, including realignment of the channel, removing contaminated sediments, adding fish habitat and revegetating the banks, and reconstructing access roads, bridge, and parking areas. An anticipated public parking area, the interim public boat launch, and the Yellowknife Historical Museum are in an area shaded in green to denote public use. A green line to those areas shows the public use roadway. Parallel to this line and extending into the orange shaded area, an orange dashed line delineates roadways for remediation use. A red diamond on the road toward the museum shows where traffic control will be set up. In Yellowknife Bay, 28 mooring locations are also marked.
